In the vast white expanse of Antarctica, there is a more alternative species - Antarctic scale shrimp. This is a species that has attracted the attention of many countries, sending special boats to fish, and our country is also involved in it and may become the strongest dark horse! What kind of shrimp can make the world compete at the same time?

<h1 class="pgc-h-arrow-right" data-track="3" > the growth characteristics of Antarctic scaly shrimp</h1>
Are Antarctic scaly shrimp a genus of shrimp? No, it is the scaly shrimp family of arthropods, with a body length of about 60 mm, and even the longest one is only close to 90 mm. The biggest difference with other shrimp animals is that the gills of Antarctic krill are visible to the naked eye and have their own light emitters, which can emit light every 3 seconds or so, personally guessing that perhaps in Antarctica, scaly shrimp rely on light emitters to find the food they need in their bodies, so what is the specific role of these lights for Antarctic krill? As of now, it is only an unknown.
Another feature of this Antarctic krill is that it has no spine, lives in groups, and as a relatively small animal in the ocean, their lifespan is about 6 years, playing an important role in the Antarctic biosphere. In terms of material energy, they are probably the most successful species on Earth. Antarctic krill feed mainly on phytoplankton in the ocean, which are grated by them and digested directly.
In terms of breeding rate and number, Antarctic krill is also in the top ten of the list, for which it has also won the reputation of "gold mine of the sea", because all organisms living in Antarctica will take Antarctic krill as their main food source, it can be said that this humble krill has high use value! In addition, it contains very high protein and a variety of mineral elements, including amino acids and high proteins needed by the human body, Antarctic krill is a treasure-filled species in nature for humans!

<h1 class="pgc-h-arrow-right" data-track="35" > Which countries have mined Antarctic scaly shrimp?</h1>
Since antarctic scaly shrimp has such a high status in the Antarctic ecosystem, many countries have also set their sights on the delicious "cake" of Antarctic scaly shrimp and want to share a piece of the pie at all costs. For this krill was first mined, the main players at that time were only Big Brother of the Soviet Union and Little Japan. The mining and fishing technology of these two countries was very advanced at that time, with the Soviet Union having the largest number of mining and fishing, reaching ninety-three percent, and Japan only seven percent.
However, it is worth mentioning that due to the collapse of the Soviet Union in the early 1980s, Japan became a large fishing country for Antarctic krill, with nearly 540,000 tons of fishing at that time. So, which countries have come to power after Japan? It was Norway, with the continuous development of mining and fishing technology, the fierce competition intensified, Japan could not sit in the first place, and was eventually replaced by Norway, but among the countries involved in fishing and mining at that time, China and South Korea also joined!

<h1 class="pgc-h-arrow-right" data-track="37" > China joined the Antarctic krill fishing army and became a dark horse</h1>
China joined the fishing and mining team relatively late to Japan, even so, China's fishing and mining speed is also the fastest, in the Antarctic mining and fishing operations, China from the beginning of only one ship, developed to the next 5, and in 2019, China also independently built a huge deep blue to join the Antarctic fishing army, with the addition of deep blue, the number and speed of Antarctic fishing krill have also been significantly improved!
Although up to now, the world's 5 giants have signed an agreement to stop fishing Antarctic krill, but for China, the number of mined and caught is the largest, has become the biggest beneficiary!

<h1 class="pgc-h-arrow-right" data-track="41" > so why do countries around the world want to mine and fish Antarctic scale shrimp at all costs?</h1>
<h1 class="pgc-h-arrow-right" data-track="42" >1, all natural antioxidants</h1>
We mentioned earlier that Antarctic krill is a highly nutritious organism, its body is not only rich in minerals, protein, but also contains astaxanthin, to know that astaxanthin this thing is the best natural antioxidant, can improve the immunity of the organism, promote biological growth and development.
For example, in this world's most expensive fish is salmon, many salmon will become not fresh after flowing into the market, especially to the table, the fishy smell emitted masks their freshness, so in order to improve the glossy color of salmon, many merchants will use Antarctic krill as an additive, because the astaxanthin in Antarctic krill can improve the color of salmon, so that it can be kept fresh for a long time and also improve the nutritional value of salmon. In addition, there are other breeding enterprises that will also improve the freshness of food and improve the nutritional value of food through Antarctic scale shrimp.

2. Magnesium in the body has high medicinal value
Antarctic krill is rich in magnesium in the body, to know that this special element has a good regulatory effect on patients with cardiovascular and cerebrovascular diseases, many pharmaceutical companies will deeply process it, extract the magnesium element in it, let it reduce the cholesterol content in the human body, and prevent arteriosclerosis and blockage of blood vessels! At the same time, it can also regulate blood pressure very well! In addition, the phosphorus and calcium contained in antarctic krill have a great help for pregnant women, the elderly and children.
3. Organisms with the highest protein content
Of all the species known to date, Antarctic krill is the organism with the highest protein content! It contains more than 50% of protein in the body, it can be said that this high-protein thing is the best gift of nature to human beings, in addition, the fatty acids contained in the Antarctic krill body have a good effect on the body's bone development and vision! Especially for children, in the process of growth and development, eating this special scale shrimp on weekdays has great benefits for the body. Therefore, in the eyes of all countries in the world, Antarctic krill has important mining and fishing value!

Although Antarctic krill has such a high catch value, the consequences for us if they are overfished are extremely serious. Not only will completely break the food chain of the Antarctic ecosystem, but also make the entire Antarctic ecosystem ecological degradation, with the intensification of overfishing, the number of Antarctic krill will gradually decrease, and other Antarctic organisms will also be threatened by food lack, so if you want to rationally mine and catch Antarctic krill, you must know how to stop, Antarctic krill is the best and highest nutrient given by nature to humans, for humans to take a degree, is the ultimate wise move!
